The relationship between pregnancy intention and alcohol use behavior: An analysis of PRAMS data

Interconnections between unintended pregnancy, alcohol and other drug use, and pregnancy, birth, infant, childhood and socioeconomic outcomes: a scoping review

BACKGROUND

Unintended pregnancy (UIP) and substance use disorder share underlying root causes with similar impacts for women and their offspring in pregnancy, birth and beyond. Furthermore, intoxication with alcohol and other drugs (AOD) increases the risk of UIP.

OBJECTIVES

To assess the available evidence on associations between UIP and health, social and economic outcomes, in women who use AOD.

SEARCH STRATEGY

The review utilised the Joanna Briggs Institute Methodology for Scoping Reviews and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) reporting guidelines. The search was conducted across multiple databases, including Scopus and Medline, and limited to studies published between January 2000 to June 2023.

SELECTION CRITERIA

Studies reporting on interactions between AOD use and UIP, and pregnancy, birth, infant, childhood, social or economic outcomes. All patterns and types of AOD use, except isolated use of tobacco, were included. Studies were available in English and conducted in high-income countries.

DATA COLLECTION AND ANALYSIS

Selected articles were reviewed, and data collected by two independent reviewers using a standardised data extraction sheet. Findings were summarised and reported descriptively.

MAIN RESULTS

A total of 2536 titles and abstracts were screened, 97 full texts were reviewed, and three studies were selected for inclusion in the scoping review. There was heterogeneity in types and patterns of AOD use, differences in study design and tools to assess pregnancy intention, and each focused on disparate outcomes. No study assessed or reported on birth outcomes.

CONCLUSION

There is a paucity of data examining the intersection between AOD use and UIP and further research is needed.

Integration of a facilitated access pathway for contraception into alcohol and other drug treatment services: A cohort study comparing metropolitan and regional settings

INTRODUCTION

Women who attend alcohol and other drug (AOD) services experience higher rates of unintended pregnancy, and access less contraception, than the general population. This study aims to observe contraceptive initiation and use after contraception services were offered at metropolitan and regional AOD services.

METHODS

Clinical staff were provided contraception education. One hundred women aged 16-49 were recruited from two services between 2017 and 2021. Women completed a questionnaire on their obstetrics and gynaecological history, pregnancy plans and contraception use. Women were provided education on contraception options and offered referral to a contraception pathway. The primary outcome was initiation of highly reliable contraception; secondary outcomes were the types of contraception initiated, and contraception use and pregnancy at 12 months. We compared the initiation of contraception across the two study sites.

RESULTS

At baseline, 91% of women were not planning a pregnancy within 12 months, with 21% of these using highly reliable contraception. Of all women not planning a pregnancy, 28% initiated highly reliable contraception via the pathway (2% metropolitan, 51% regional, p < 0.001), with intrauterine devices being the most frequent method initiated (15%). At 12 months, 44% were using highly reliable contraception and 15% had recorded pregnancies.

DISCUSSION AND CONCLUSIONS

Contraception pathways for women in AOD treatment can improve initiation of highly reliable methods of contraception, although pregnancy rates were still high and there were large differences between the study sites. Care navigation and clinical champions are some potential facilitators to contraception access, and understanding additional barriers to access may be useful.

The effect of changing pregnancy intentions on preconception health behaviors: a prospective cohort study

PURPOSE

Pregnancy intentions are associated with preconception health behaviors but are understudied among female adolescent and young adult (AYA) cancer survivors. Preconception health is critical for survivors because they face unique risks to fertility and pregnancy from late effects of cancer treatments. This study prospectively assessed the effect of pregnancy intention on physical activity (PA) and smoking behaviors among female AYA survivors.

METHODS

A cohort of 1049 female AYA survivors were recruited between 2013 and 2017. Participants were 18-39 years and had completed primary cancer treatment. Longitudinal mixed effects analysis was conducted on participants who completed at least 2 of 4 questionnaires over 1.5 years. Two measures were used to capture multiple dimensions of pregnancy intention. The pregnancy intention score (PIS) captured wanting and planning dimensions and represented a scaled response of low to high intention. The trying dimension captured urgent intention and ranged from not trying, ambivalent (neither attempting nor avoiding pregnancy), and trying now. Intention change was assessed between each consecutive time points. Final analysis was conducted with multiple imputations.

RESULTS

Survivors with increased intention measured by trying was associated with increased PA over time (adjusted B [95%CI]: 0.3 [0.01, 0.5]) compared to survivors with no changes or decreased trying intention. PIS was not significantly associated with preconception behaviors. No measure of intention was associated with smoking behavior.

CONCLUSIONS

Increasingly urgent pregnancy intention (trying dimension) was associated with higher preconception PA.

IMPLICATIONS FOR CANCER SURVIVORS

Screening for immediate intentions can identify AYA survivors in need of early preconception health promotion.

Intimate Partner Violence and Children: Essentials for the Pediatric Nurse Practitioner

Intimate partner violence (IPV) is a public health problem of epidemic proportions. IPV often starts early in adolescence and continues throughout an individual's lifespan. IPV is defined as abuse or aggression occurring in the context of a romantic relationship that is perpetrated by a current or former partner. IPV victims often experience severe psychological trauma, physical injury, and even death. The direct recipient of the violence is often not the only individual impacted. Children are often peripheral victims of IPV. It is vital that pediatric health care providers, including pediatric nurse practitioners, recognize that IPV is indeed a pediatric health care crisis requiring strategies for both identification and intervention. This continuing education article will discuss IPV and its impact on children from conception to adolescence while exploring implications for practice.

Association between pregnancy intention and preconception health behaviors

BACKGROUND

Female adolescent and young adult (AYA) cancer survivors face higher infertility and pregnancy risks than peers with no cancer history. Preconception health behaviors such as physical activity (PA), tobacco smoking, and alcohol intake influence reproductive outcomes. In general populations, pregnancy intention is positively associated with healthy preconception behaviors, but it has not been studied among AYA survivors. The authors hypothesized that higher pregnancy intention would be associated with healthier behaviors, especially among AYA survivors with perceived infertility risk.

METHODS

A cross-sectional analysis was conducted with data collected between 2013 and 2017 from 1071 female AYA survivors aged 18 to 39 years who had completed their primary cancer treatment and enrolled in an ovarian function study. Self-reported intention dimensions were measured as a pregnancy intention score (PIS) and trying now to become pregnant. Multivariable linear (PA), binary (smoking), and ordinal (alcohol use) logistic regressions were used to estimate associations between intentions and preconception behaviors, with adjustments made for demographic and cancer characteristics. Effect modification by perceived infertility risk was assessed.

RESULTS

The mean PIS was 1.1 (SD, 0.77) on a 0 to 2 scale (2 = high intention), and 8.9% were attempting pregnancy now. A higher PIS was associated with increased PA (β, 0.08; 95% CI, 0.11-1.04), whereas ambivalence in pregnancy intention was associated with lower alcohol consumption (odds ratio, 0.72; 95% CI, 0.55-0.95). Pregnancy intentions were not associated with smoking. Perceived infertility risk strengthened the relationship between PIS and PA (P < .05).

CONCLUSIONS

Pregnancy intentions were associated with some healthier preconception behaviors in AYA survivors. Medical professionals caring for AYA survivors may consider pregnancy intention screening to guide conversations on preconception health.

Preconception Substance Use and Risk of Unintended Pregnancy: Pregnancy Risk Assessment Monitoring System 2016-17

OBJECTIVE

This study examined the association between preconception substance use and unintended pregnancy in a large, nationally representative sample of women.

METHODS

In this cross-sectional study, we used data from the Pregnancy Risk Assessment Monitoring System (PRAMS) comprising, 74,543women who had birth during 2016-17. Logistic regression was used to assess the independent association of unintended pregnancy overall and by subtypes to preconception substance use (smoking and other nicotine/tobacco use, alcohol consumption, and use of cannabis, illicit/recreational drugs) and specific medication including prescription opioids, antidepressants and over the counter pain relief.

RESULTS

Overall, 41% of pregnancies were unintended. Nearly 57% of participants reported alcohol consumption during the preconception period, with 32% indicating binge drinking, 17% reported preconception smoking, and 10% cannabis use. Unintended pregnancy was significantly associated with substance use, including smoking (adjusted odds ratio [AOR]:1.5, 95% confidence interval [CI]: 1.4-1.6); as well as the use of other nicotine/tobacco (AOR:1.4, 95% CI: 1.3-1.5); cannabis (AOR: 1.9, 95% CI: 1.5-2.3); illicit/recreational drugs (AOR:1.7, 95% CI: 1.2-2.4), prescription opioids (AOR:1.4, 95% CI: 1.02-1.9), and prescription antidepressants (AOR 1.8, 95% CI: 1.1-3.0). The likelihood of unintended pregnancy was significantly elevated with heavy smoking, heavy alcohol consumption, and binge drinking. Analyses by unintended pregnancy subtype yielded similar results.

CONCLUSIONS

Preconception substance use was significantly and positively associated with unintended pregnancy. Evidence-based interventions are needed addressing substance use behavior and effective contraceptive use to prevent unintended pregnancy and related adverse effects on maternal and child health.

Association of Pregnancy Intentions With Substance Use During Early Pregnancy

OBJECTIVES

The goal of this study was to evaluate the association between pregnancy intentions and substance use in early pregnancy among pregnant women receiving prenatal care in a large, integrated healthcare system.

METHODS

The sample comprised 29,787 Kaiser Permanente Northern California pregnant women (12.1% aged <25, 36.4% non-Hispanic White) screened for prenatal substance use in 2018 via a self-reported questionnaire and urine toxicology test given as part of standard prenatal care (at ∼8 weeks gestation). Multivariable logistic regression models tested for associations of pregnancy intentions with prenatal substance use (any use and specific substances) by self-report and/or a positive urine toxicology test.

RESULTS

Adjusting for covariates, women with an unintended pregnancy (23.9% of the sample) had higher odds of any prenatal substance use than women with an intended pregnancy (28.8% vs 16.1%; adjusted odds ratio [aOR] = 1.80, 95% confidence interval [CI]:1.67-1.93). Having an unintended pregnancy was also associated with higher odds of using alcohol (14.4% vs 10.4%; aOR = 1.73, 95%CI:1.59-1.89), cannabis (15.6% vs 5.6%; aOR = 1.91, 95%CI:1.73-2.11), nicotine (3.8% vs 1.3%; aOR = 2.33, 95%CI:1.92-2.82), pain medication (2.3% vs 1.2%; aOR = 1.64, 95%CI:1.32-2.03), and stimulants (0.8% vs 0.3%; aOR = 1.85, 95%CI:1.23-2.79) early in pregnancy.

DISCUSSION

Having an unintended pregnancy was associated with higher odds of substance use during early pregnancy. Connecting women of reproductive age with health education about pregnancy prevention and recognition of early signs of pregnancy, effective contraception, and early screening and interventions for prenatal substance use may help to reduce prenatal substance use and its associated consequences.

Maternal adverse childhood experiences and pregnancy intentions

PURPOSE

The current study investigates the association between maternal adverse childhood experiences (ACEs) and having an unwanted (i.e., a pregnancy that was undesired) or mistimed pregnancy (i.e., a pregnancy that occurred sooner than wanted).

METHODS

Data are from the 2018 North Dakota and South Dakota Pregnancy Risk Assessment Monitoring System (PRAMS) (N = 1897). Multinomial logistic regression analyses are used to assess the association between levels of ACE exposure and having an unwanted or mistimed pregnancy relative to an intended pregnancy.

RESULTS

Findings demonstrated that women with three ACEs (Relative Risk Ratio [RRR] = 2.157, 95% confidence interval [CI], 1.121-4.151) and four or more ACEs (RRR = 1.836, 95% CI, 1.181-2.854) had approximately twice the relative risk of having an unwanted pregnancy (vs. an intended pregnancy) compared to women with 0 ACEs. There was no association between ACEs and reporting a mistimed pregnancy.

CONCLUSIONS

These findings add to a burgeoning literature detailing how accumulating ACEs can create challenges for family planning by increasing the likelihood of having an unintended pregnancy. Study results suggest the need to devote greater resources to the prevention of ACEs and unintended pregnancies.

The association between alcohol intake and fecundability during menstrual cycle phases

STUDY QUESTION

Is increased alcohol intake in different phases of the menstrual cycle associated with fecundability in women?

SUMMARY ANSWER

Heavy intake (>6 drinks/week) of alcoholic beverages in the luteal phase and ovulatory subphase was associated with reduced odds of conception; moderate intake (3-6 drinks/week) during the luteal phase was also associated with reduced fecundability.

WHAT IS KNOWN ALREADY

Despite strong indications for increased risk of infertility among drinking women with intention to conceive, inconsistencies in previous results point to possible residual confounding, and have not thoroughly investigated timing of drinking and other drinking patterns during the menstrual cycle.

STUDY DESIGN, SIZE, DURATION

Participants in The Mount Sinai Study of Women Office Workers (MSSWOW), a prospective cohort study of fertility, were recruited and followed between 1990 and 1994, and completed daily diaries reporting their alcohol intake (type and number of drinks) for a maximum of 19 months of follow-up (N = 413).

PARTICIPANTS/MATERIALS, SETTING, METHODS

Participants were between 19 and 41 years of age. After completion of baseline surveys, they were asked to record their alcoholic beverage intake as number of drinks of beer, wine, and liquor per day, in addition to other exposures such as caffeine and smoking. Furthermore, they submitted urine samples each month to assess pregnancy. Menstrual cycle phases were calculated using the Knaus-Ognio approach. Discrete survival analysis methods were employed to estimate the association between categories of alcohol intake in each phase of menstrual cycle and fecundability.

MAIN RESULTS AND THE ROLE OF CHANCE

In the luteal phase, both moderate drinking (3-6 drinks/week, Fecundability Odds Ratio (FOR)=0.56, CI: 0.31, 0.98) and heavy drinking (>6 drinks/week, FOR = 0.51, CI: 0.29, 0.89) were associated with a reduction in fecundability, compared to non-drinkers. For the follicular phase, heavy drinking in the ovulatory sub-phase (FOR = 0.39, CI: 0.19, 0.72) was similarly associated with reduced fecundability, compared to non-drinkers. For the pre-ovulatory sub-phase, heavy drinking (>6 drinks/week, FOR = 0.54, CI: 0.29, 0.97) was associated with reduction in fecundability, but this association was inconsistent when subjected to sensitivity tests. Each extra day of binge drinking was associated with 19% (FOR = 0.81, CI: 0.63, 0.98), and 41% (FOR = 0.59, CI: 0.33, 0.93) reduction in fecundability for the luteal phase and ovulatory sub-phase respectively, but no association was observed in the pre-ovulatory sub-phase. No meaningful differences in fecundability between beverages were observed in any menstrual phase.

LIMITATIONS, REASONS FOR CAUTION

Patterns of alcohol intake in this cohort suggest a lower average alcohol intake compared to more recent national averages for the same demographic group. Sample sizes were small for some subgroups, resulting in limited power to examine specific beverage types in different phases of the menstrual cycle, or to assess interaction. In addition, the influence of male partner alcohol intake was not assessed, the data relied on self-report, and residual confounding (e.g. unmeasured behaviors correlated with alcohol intake) is a possibility.

WIDER IMPLICATIONS OF THE FINDINGS

Results suggest an inverse association between alcohol and fecundability, and support the relevance of menstrual cycle phases in this link. More specifically, moderate to heavy drinking during the luteal phase, and heavy drinking in the ovulatory window, could disturb the delicate sequence of hormonal events, affecting chances of a successful conception.

Intimate partner violence and the association of pregnancy intendedness - A cross-sectional study in southeastern Norway

OBJECTIVES

Unintended pregnancy in the context of intimate partner violence (IPV) is a public health issue. It is associated with increased health risks for women and their children. Our objective was to investigate the association between unintended pregnancy and emotional, physical and sexual IPV in a multi-cultural population attending routine antenatal care.

STUDY DESIGN

A prospective cross-sectional study of 1788 pregnant women who filled out a questionnaire during pregnancy as part of a randomized controlled trial conducted in southeastern Norway.

MAIN OUTCOME MEASURES

Pregnancy intendedness was measured by asking women if their pregnancy was planned or not. The Abuse Assessment Screen and the Composite Abuse Scale R-SF, consisting of descriptive questions, were used to measure IPV. Chi-square tests, a Mann-Whitney U test, and binary logistic regression analysis were used.

RESULTS

Almost one in five women (17.4%) reported that their current pregnancy was unintended. Women with unintended pregnancy were significantly younger, had lower educational backgrounds, more limited economic resources and were more likely to be non-native Norwegian speakers. A total of 15.3% of the women reported some experience of IPV in their lifetime. These women were significantly more likely to experience an unintended pregnancy than women who had not experienced IPV, after adjusting for confounding factors: AOR = 1.74 (95% CI [1.23-2.47]).

CONCLUSIONS

Women who had experienced IPV were significantly more likely to have an unintended pregnancy than women who had not experienced IPV. It is of major importance to identify those women and offer appropriate services during pregnancy.

Maternal Substance Use: Consequences, Identification, and Interventions

Alcohol, tobacco, and cannabis are the substances most frequently used during pregnancy, and opioid-exposed pregnancies have increased fourfold. The purpose of this review is to describe the prevalence and consequences of prenatal exposure to alcohol, tobacco, cannabis, and opioids. Currently available screening questionnaires for prenatal substance use are summarized and contrasted with the measures available for prenatal alcohol use. Because screening for prenatal alcohol and substance use is but the prelude to efforts to mitigate the potential adverse consequences, attempts for the modification of these consequences are briefly reviewed. In addition, areas of future research related to the criminalization of prenatal substance use, which may inhibit both inquiry and disclosure, are discussed. Indeed, the full potential of effective interventions has yet to be realized.

Effect of Changes in Response Options on Reported Pregnancy Intentions: A Natural Experiment in the United States

Objectives

The Pregnancy Risk Assessment Monitoring System (PRAMS), conducted by the Centers for Disease Control and Prevention in collaboration with state health departments, is the largest state-level surveillance system that includes a question on the intention status of pregnancies leading to live birth. In 2012, the question was changed to include an additional response option describing uncertainty before the pregnancy about the desire for pregnancy. This analysis investigated how this additional response option affected women’s responses.

Methods

We used the change in the pregnancy intention question in 2012 as a natural experiment, taking advantage of relatively stable distributions of pregnancy intentions during short periods of time in states. Using PRAMS data from 2009-2014 (N = 222 781), we used a regression discontinuity-in-time design to test for differences in the proportion of women choosing each response option in the periods before and after the question change.

Results

During 2012-2014, 13%-15% of women chose the new response option, “I wasn’t sure what I wanted.” The addition of the new response option substantially affected distributions of pregnancy intentions, drawing responses away from all answer choices except “I wanted to be pregnant then.” Effects were not uniform across age, parity, or race/ethnicity or across states.

Conclusions

These effects could influence estimated levels and trends of the proportion of births that are characterized as intended, mistimed, or unwanted, as well as estimates of differences between demographic groups. These findings will help to inform new strategies for measuring pregnancy and childbearing desires among women.

Is Periconceptional Substance Use Associated with Unintended Pregnancy?

Background: To evaluate the relationship between periconceptional (period before and/or after conception) substance use and unfavorable pregnancy contexts, including unintended pregnancy.

Materials and Methods: This is a cross-sectional analysis of English- or Spanish-speaking women aged 16–44 years with pregnancies <24 weeks' gestation presenting to pregnancy testing clinics and enrolled between June 2014 and June 2015. Participants self-reported periconceptional substance use (tobacco, alcohol, marijuana, and other illicit substances during the 3 months before enrollment), and pregnancy “contexts,” including pregnancy intention, wantedness, planning, timing, desirability, and happiness. Multivariable logistic regression was performed adjusting for potential confounding variables.

Results: We enrolled 123 women, averaging 27 ± 6 years, and mean gestational age 7.5 ± 3.0 weeks. Most participants were black, non-Hispanic (37%), or Hispanic (46%), and chose to complete the study in English (69%). Sixty-five percent participants reported use of one or more substances during prior 3 months: alcohol (54%), tobacco (31%), and marijuana (21%). In multivariate analysis, periconceptional alcohol use was associated with increased odds of unintended or ambivalent pregnancy and unwanted or mixed feelings regarding pregnancy (odds ratios [OR] = 3.29, 95% confidence interval [CI] 1.08–10.08 and OR = 2.81, 95% CI 1.07–7.36, respectively). Weekly or daily tobacco use was associated with unhappiness about pregnancy (OR = 7.56, 95% CI 1.65–34.51) and undesired or unsure pregnancy (OR = 4.00, 95% CI 1.14–14.06).

Conclusions: Periconceptional alcohol or tobacco use demonstrates increased odds of specific unfavorable pregnancy contexts, including pregnancy described as undesired, unintended, unwanted, and unhappiness with pregnancy. Primary prevention of periconceptional substance use and the negative effects of alcohol and tobacco may be improved by increasing contraception access for women at risk for unfavorable pregnancy contexts.

Identification of substance use disorders among pregnant women: A comparison of screeners

BACKGROUND

The purpose of this study is to evaluate five self-report, non-proprietary questionnaires in the identification of substance use disorders [including alcohol, cannabis, opioids, and stimulants] among pregnant women.

PROCEDURES

A total of 1220 pregnant women completed the NIDA Quick Screen, CRAFFT, Substance Use Risk Profile-Pregnancy (SURP-P), Wayne Indirect Drug Use Questionnaire (WIDUS), and the 5 Ps, as well as the MINI diagnostic interview for substance use disorders, which served as the reference standard. Measures of merit calculated for each screener included sensitivity, specificity, accuracy, and area under the receiver operating curve (AUROC).

MAIN FINDINGS

The participants were socioeconomically diverse, with a mean age of 29 years. Over 15% met diagnostic criteria for a substance use disorder. AUROCS for identifying any substance use disorder (including alcohol) ranged from a high of 0.75 for the CRAFFT (95% CI = 0.72-79) and 0.74 for the SURP-P (95% CI = 0.71-.78) to a low of 0.62 for the NIDA Quick Screen (95% CI = 0.59-.65). Overall accuracy of most tested measures was higher for identification of alcohol use disorders than for other substance use disorders (e.g., AUROCs for the CRAFFT and SURP-P for identifying alcohol use disorders were 0.78 and 0.77, respectively).

PRINCIPAL CONCLUSIONS

The CRAFFT and SURP-P showed modest ability to identify substance use disorders among pregnant women. Future research is needed to develop an ideal questionnaire set in the complicated societal context which includes increasing rates of use and potential sanction.

Associated Factors of Drinking Prior to Recognising Pregnancy and Risky Drinking among New Zealand Women Aged 18 to 35 Years

Nearly half of all pregnant women in the Western world drink prior to recognising pregnancy. The current study aimed to investigate the factors associated with drinking prior to recognising pregnancy among pregnant women and factors associated with risky drinking among nonpregnant sexually active women. The study was a cross-sectional survey of a random sample of women aged 18 to 35 years (n = 1062) selected from the New Zealand electoral roll. Pregnant women (currently pregnant: n = 65; previously pregnant: n = 202) who were risky drinkers and who smoked in the year prior to pregnancy had five times the odds (p < 0.01) and women who planned their pregnancy (p = 0.05) and who used a community service card (p = 0.004) had less than half the odds to drink prior to recognising pregnancy than their respective counterparts. Among sexually active nonpregnant women who consumed alcohol, those who smoked in the year prior to the survey and those who drank for social reasons, for mood enhancement or coping reasons had higher odds of being risky drinkers (p < 0.05). Addressing risky drinking, especially in social settings, and smoking among women of peak childbearing age may mitigate the potential risk of drinking prior to recognising pregnancy.

Prevalence of alcohol use in pregnant women with substance use disorder

BACKGROUND

Prenatal care programs for women with opioid use disorder (OUD) often focus treatment/counseling plans around illicit substances, while concurrent use of alcohol might present an equal or greater risk to the fetus.

METHODS

This study evaluated self-reported prevalence of alcohol use in patients participating in a comprehensive prenatal care program for women with substance use disorder (SUD; n = 295), of which 95% are treated for OUD, and pregnant women being served through general obstetrical clinics at the University of New Mexico (n = 365). During the screening phase of a prospective study, patients were asked to report alcohol use in the periconceptional period, and between the last menstrual period and pregnancy recognition.

RESULTS

The screening interview was conducted at 22.3 (median = 22; Q1 = 16; Q3 = 29) gestational weeks. Among patients screened at the SUD clinic, 28.8% and 24.1% reported at least one binge drinking episode in the periconceptional period and in early pregnancy, respectively. The prevalence of binge drinking was similar in the general obstetrics population (24.7% and 24.4%, respectively). Among those who reported drinking in early pregnancy, median number of binge drinking episodes was higher among patients screened at the SUD clinic (median = 3; Q1 = 1; Q3 = 10) compared to the general obstetrics group (median = 1; Q1 = 1; Q3 = 3; p < 0.001).

CONCLUSIONS

This study demonstrates a high prevalence of prenatal alcohol use in early pregnancy in both groups, while patients with SUD/OUD consume more alcohol. These findings underscore the need for targeted screening and intervention for alcohol use in all pregnant women, especially those with SUD/OUD.

Postpartum Contraceptive use and Rapid Repeat Pregnancy Among Women who use Substances

BACKGROUND

Postpartum contraception is especially important for women who use alcohol and other substances, given the risk of possible rapid repeat pregnancy and prenatal substance exposure. However, little is known about postpartum contraceptive use among women with substance use histories.

OBJECTIVE

To characterize postpartum contraceptive initiation, 24-month continuation, and rapid repeat pregnancy among women who used substances during pregnancy.

METHODS

This is a secondary analysis of 161 pregnant women who enrolled in a randomized clinical trial to treat substance use in pregnancy and completed at least one follow-up assessment. Women were eligible if they were less than 28 weeks gestation and reported alcohol or illicit drug use within the past 30 days. Participants were recruited from two hospital-based OB/GYN clinics between 2006 and 2010, and completed assessments at delivery and 3-, 12-, and 24-months postpartum.

RESULTS

Past 30-day use of any substance (not including tobacco) was 52.4%, 58.3%, and 59.8% at 3-, 12-, and 24-month follow-up, respectively. Marijuana was the most commonly reported illicit substance (as high as 48.1%). Rates of any contraceptive use were 71.3%, 66.7% and 65.3% at 3-, 12-, and 24-month follow-up, respectively; DepoProvera and condoms were the most common methods. Rapid repeat pregnancy occurred in 28% of participants by 24-month follow-up. Conclusions/Importance: Postpartum contraceptive use among substance using women was at or near 70%, which is comparable to other samples of postpartum women. Innovative efforts are needed to promote effective contraceptive use among postpartum women in general and among those who use substances in particular.

Pregnancy Intention and Maternal Alcohol Consumption

OBJECTIVE

To evaluate whether women planning a pregnancy are less likely to use alcohol in early pregnancy than those with unintended pregnancies.

METHODS

Right From the Start (2000-2012) is a prospective, community-based pregnancy cohort. Maternal demographic, reproductive, and behavioral data were collected in telephone interviews at enrollment (mean±standard deviation 48±13 days of gestation) and later in the first trimester (mean±standard deviation 85±21 days of gestation). Alcohol consumption characteristics were included in the interviews. We used logistic regression to investigate the association of pregnancy intention with alcohol use.

RESULTS

Among 5,036 women, 55% reported using alcohol in the first trimester with 6% continuing use at the first-trimester interview. Pregnancy was planned by 70% of participants. Alcohol use occurred in 55% and 56% of intended and unintended pregnancies, respectively (P=.32). Adjusting for confounders, women with intended pregnancies were 31% less likely to consume any alcohol in early pregnancy (adjusted odds ratio [OR] 0.69, 95% confidence interval [CI] 0.60-0.81) or binge drink (adjusted OR 0.68, 95% CI 0.54-0.86). Most women, regardless of intention, stopped or decreased alcohol consumption in early pregnancy.

CONCLUSION

The majority of women, irrespective of intention, stopped or decreased drinking after pregnancy recognition. This suggests promoting early pregnancy awareness could prove more effective than promoting abstinence from alcohol among all who could conceive.

Peri-Conceptual and Mid-Pregnancy Alcohol Consumption: A Comparison between Areas of High and Low Deprivation in Scotland

BACKGROUND

Alcohol-related mortality and morbidity among women has increased over recent decades, especially in areas of higher deprivation. Pre-pregnancy alcohol use is associated with continued consumption in pregnancy. We assessed whether general population alcohol consumption patterns were reflected among pregnant women in two Scottish areas with different deprivation levels.

METHODS

Cross-sectional study in two health boards (HB1, lower deprivation levels, n = 274; HB2, higher deprivation levels, n = 236), using face-to-face 7-day Retrospective Diary estimation of peri-conceptual and mid-pregnancy alcohol consumption.

RESULTS

A greater proportion of women in HB2 (higher deprivation area) sometimes drank peri-conceptually, but women in HB1 (lower deprivation area) were more likely to drink every week (49.6 vs 29.7%; p < 0.001) and to exceed daily limits (6 units) at least once each week (32.1 vs 14.8%; p < 0.001). After pregnancy recognition, consumption levels fell sharply, but women in HB2 were more likely to drink above recommended daily limits (2 units) each week (2.5 vs 0.0%; p < 0.05). However, women in HB1 were more likely to drink frequently. Women with the highest deprivation scores in each area drank on average less than women with the lowest deprivation scores.

CONCLUSIONS

Heavy episodic and frequent consumption was more common in the lower deprivation area, in contrast with general population data. Eliciting a detailed alcohol history at the antenatal booking visit, and not simply establishing whether the woman is currently drinking, is essential. Inconsistent messages about the effects of alcohol in pregnancy may have contributed to the mixed picture we found concerning peri-conceptual and mid-pregnancy alcohol consumption.

Evaluation of a retrospective diary for peri-conceptual and mid-pregnancy drinking in Scotland: a cross-sectional study

INTRODUCTION

Heavy episodic ("binge") drinking among women in Scotland is commonplace; prepregnancy drinking is associated with continued antenatal drinking. Evidence for effectiveness of standardized antenatal alcohol assessment is lacking. Alcohol-exposed pregnancies may be missed. We assessed peri-conceptual and mid-pregnancy consumption using a week-long retrospective diary and standard alcohol questionnaires, and evaluated the agreement between these instruments.

MATERIAL AND METHODS

Cross-sectional study in two Scottish health board areas involving 510 women attending mid-pregnancy ultrasound scan clinics. Face-to-face administration of alcohol retrospective diary and AUDIT or AUDIT-C assessed weekly and daily alcohol consumption levels and patterns. Depression-Anxiety-Stress Scale (DASS-21) assessed maternal wellbeing. A sub-sample (n = 30) provided hair for alcohol metabolite analysis. Pearson's correlation coefficient investigated associations between questionnaires and alcohol metabolite data.

RESULTS

The response rate was 73.8%. The retrospective diary correlated moderately with AUDIT-C and AUDIT but elicited reports of significantly higher peri-conceptual consumption, (median unit consumption on "drinking days" 6.8; range 0.4-63.8). Additional "special occasions" consumption ranged from 1 to 125 units per week. Correlations between DASS-21 and retrospective diary were weak. Biomarker analysis identified three instances of hazardous peri-conceptual drinking.

CONCLUSIONS

Women reported higher consumption levels when completing the retrospective diary, especially regarding peri-conceptual "binge" drinking. Routine clinical practice methods may not capture potentially harmful or irregular drinking patterns. Given the association between prepregnancy and antenatal drinking, and alcohol's known teratogenic effects, particularly in the first trimester, the retrospective diary may be a useful low-tech tool to gather information on alcohol intake patterns and levels.

Peri-conceptual and mid-pregnancy drinking: a cross-sectional assessment in two Scottish health board areas using a 7-day Retrospective Diary

AIMS

The aim of this study was to evaluate the use of a 7-day Retrospective Diary to assess peri-conceptual and mid-pregnancy alcohol consumption.

BACKGROUND

Alcohol consumption among women has increased significantly and is of international concern. Heavy episodic ('binge') drinking is commonplace and is associated with unintended pregnancy. Pre-pregnancy drinking is strongly associated with continued drinking in pregnancy. Routine antenatal assessment of alcohol history and current drinking is variable; potentially harmful peri-conceptual drinking may be missed if a woman reports low or no drinking during pregnancy.

DESIGN

Cross-sectional study (n = 510) in two Scottish health board areas.

METHODS

Face-to-face Retrospective Diary administration from February to June 2015 assessing alcohol consumption in peri-conceptual and mid-pregnancy periods. Women were recruited at the mid-pregnancy ultrasound clinic.

RESULTS

Of 510 women, 470 (92·0%) drank alcohol before their pregnancy; 187 (39·9%) drank every week. Retrospective assessment of peri-conceptual consumption identified heavy episodic drinking (more than six units on one occasion) in 52·2% (n = 266); 19·6% (n = 100) reported drinking more than 14 units per week, mostly at the weekend; 'mixing' of drinks was associated with significantly higher consumption. While consumption tailed off following pregnancy recognition, 5·5% (n = 28) still exceeded the recommended daily two-unit limit in pregnancy. Multivariable logistic regression identified that women who 'binged' peri-conceptually were 3·2 times more likely to do this.

CONCLUSION

Statistically significant peri-conceptual consumption levels suggest a substantial proportion of alcohol-exposed pregnancies before pregnancy recognition. Not taking a detailed alcohol history, including patterns of consumption, will result in under-detection of alcohol-exposed pregnancies. The Retrospective Diary offers practitioners a detailed way of enquiring about alcohol history for this population.

Health insurance, alcohol and tobacco use among pregnant and non-pregnant women of reproductive age

BACKGROUND

Understanding the relationship between health insurance coverage and tobacco and alcohol use among reproductive age women can provide important insight into the role of access to care in preventing tobacco and alcohol use among pregnant women and women planning to become pregnant.

METHODS

We examined the association between health insurance coverage and both past month alcohol use and past month tobacco use in a nationally representative sample of women age 12-44 years old, by pregnancy status. The women (n=97,788) were participants in the National Survey of Drug Use and Health (NSDUH) in 2010-2013. Logistic regression models assessed the association between health insurance (insured versus uninsured), past month tobacco and alcohol use, and whether this was modified by pregnancy status.

RESULTS

Pregnancy status significantly moderated the relationship between health insurance and tobacco use (p-value≤0.01) and alcohol use (p-value≤0.01). Among pregnant women, being insured was associated with lower odds of alcohol use (adjusted odds ratio [AOR]=0.47; 95% confidence interval [CI]=0.27-0.82), but not associated with tobacco use (AOR=1.14; 95% CI=0.73-1.76). Among non-pregnant women, being insured was associated with lower odds of tobacco use (AOR=0.67; 95% CI=0.63-0.72), but higher odds of alcohol use (AOR=1.23; 95% CI=1.15-1.32).

CONCLUSION

Access to health care, via health insurance coverage is a promising method to help reduce alcohol use during pregnancy. However, despite health insurance coverage, tobacco use persists during pregnancy, suggesting missed opportunities for prevention during prenatal visits.

Which women are missed by primary health-care based interventions for alcohol and drug use?

BACKGROUND

Women of reproductive age who binge drink or have alcohol-related problem symptoms (APS) and who do not use contraception are considered at risk of an alcohol-exposed pregnancy (AEP). In the U.S., efforts to prevent AEPs focus largely on delivering interventions in primary health care settings. While research suggests that these interventions are efficacious for women reached, it is unclear to what extent these interventions are likely to reach women at risk of AEPs.

METHODS

Data are from the Turnaway Study, a study of 956 women seeking pregnancy termination at 30 U.S. facilities between 2008 and 2010, some of whom received and some of whom were denied terminations because they were past the gestational limit. We examined associations between binge drinking, APS, and drug use prior to pregnancy recognition and having a usual source of health care (USOC).

RESULTS

Overall, 59% reported having a USOC. A smaller proportion with than without an APS reported a USOC (44 vs. 60%, p<.05) and a smaller proportion using than not using drugs reported a USOC (51 vs. 61%, p<.05). This pattern was not observed for binge drinking. In multivariate analyses, an APS continued to be associated with lack of a USOC, while drug use was no longer associated with lack of a USOC.

CONCLUSIONS

As more than 40% did not have a USOC, with higher proportions among women with an APS, primary health-care based approaches to AEP prevention seem unlikely to reach the majority of women who have an APS and are at risk of an unintended pregnancy.

Are pregnancy planning and timing associated with preterm or small for gestational age births?

OBJECTIVE

To investigate whether unplanned or poorly timed pregnancies (self-reported at enrollment) are associated with preterm or small for gestational age births.

DESIGN

Prospective cohort study.

SETTING

Not applicable.

PATIENT(S)

Two thousand six hundred fifty-four pregnant women <18 weeks estimated gestational age with a singleton pregnancy.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Preterm and small for gestational age births.

RESULT(S)

In adjusted analyses, pregnancy planning was not statistically significantly associated with preterm (odds ratio [OR] 1.18; 95% confidence interval [CI], 0.85-1.65) or small for gestational age birth (OR 1.17; 95% CI, 0.69-1.97). Similarly, poorly timed pregnancies were not statistically significantly associated with preterm (OR 0.85; 95% CI, 0.53-1.38) or small for gestational age birth (OR 0.92; 95% CI, 0.65-1.29). Combining pregnancy planning (yes/no) and timing (yes/no) into a 4-level category showed no statistically significant association with preterm birth or small for gestational age.

CONCLUSION(S)

In a large cohort with antenatally assessed pregnancy planning and timing, outcome data collected from medical record abstraction, and robust analysis adjusting for multiple confounding factors including maternal demographics, medical conditions, and other risk factors, neither pregnancy planning nor pregnancy timing showed a statistically significant association with preterm or small for gestational age infants. This study improves upon previous analyses that lacked adjustment for confounding and used retrospective self-reporting to assess pregnancy planning and timing, and preterm and small for gestational age births. Findings may differ in higher risk populations with higher prevalence of preterm or small for gestational age births.

Substance Use in the Perinatal Period

Perinatal substance use remains a major public health problem and is associated with a number of deleterious maternal and fetal effects. Polysubstance use in pregnancy is common and can potentiate adverse maternal and fetal outcomes. Tobacco is the most commonly used substance in pregnancy, followed by alcohol and illicit substances. The treatments for perinatal substance use are limited and consist mostly of behavioral and psychosocial interventions. Of these, contingency management has shown the most efficacy. More recently, novel interventions such as progesterone for postpartum cocaine use have shown promise. The purpose of this review is to examine the recent literature on the use of tobacco, alcohol, cannabis, stimulants, and opioids in the perinatal period, their effects on maternal and fetal health, and current treatments.

Pregnancy intendedness and the association with physical, sexual and emotional abuse - a European multi-country cross-sectional study

BACKGROUND

Unintended pregnancies are common and when not resulting in a termination of pregnancy may lead to unintended childbirth. Unintended pregnancies are associated with increased health risks, also for women for whom pregnancy continues to childbirth. Our objective was to present the prevalence of unintended pregnancy in six European countries among pregnant women attending routine antenatal care, and to investigate the association with a history of physical, sexual and emotional abuse.

METHODS

A prospective cross-sectional study, of 7102 pregnant women who filled out a questionnaire during pregnancy as part of a multi-country cohort study (Bidens) with the participating countries: Belgium, Iceland, Denmark, Estonia, Norway and Sweden. A validated instrument, the Norvold Abuse Questionnaire (NorAq) consisting of 10 descriptive questions measured abuse. Pregnancy intendedness was assessed using a single question asking women if this pregnancy was planned. Cross-tabulation, Chi-square tests and binary logistic regression analysis were used.

RESULTS

Approximately one-fifth (19.2 %) of all women reported their current pregnancy to be unintended. Women with an unintended pregnancy were significantly younger, had less education, suffered economic hardship, had a different ethnic background from the regional majority and more frequently were not living with their partner. The prevalence of an unintended pregnancy among women reporting any lifetime abuse was 24.5 %, and 38.5 % among women reporting recent abuse. Women with a history of any lifetime abuse had significantly higher odds of unintended pregnancy, also after adjusting for confounding factors, AOR for any lifetime abuse 1.41 (95 % CI 1.23-1.60) and for recent abuse AOR 2.03 (95 % CI 1.54-2.68).

CONCLUSION

Women who have experienced any lifetime abuse are significantly more likely to have an unintended pregnancy. This is particularly true for women reporting recent abuse, suggesting that women living in a violent relationship have less control over their fertility.

Alcohol use before and during unwanted pregnancy

BACKGROUND

There is little information about pregnancy-related changes in alcohol use and factors contributing to changes among women with unwanted pregnancies. This study describes changes in alcohol use from before pregnancy recognition to during pregnancy and identifies important predictors of alcohol use severity among women with unwanted pregnancies.

METHODS

Data are from the Turnaway Study of 956 women seeking pregnancy termination at 30 U.S. facilities between 2008 and 2010, some of whom were denied care because they were past the gestational limit of the facility where they were recruited and were still pregnant at the baseline interview, 1 week after termination seeking. Predictors of alcohol use severity (a latent variable) were identified.

RESULTS

About 56% of the total sample reported any alcohol use the month before pregnancy recognition, with 23% reporting 6 or more drinks on an occasion. Among the total sample, 35% of those drinking before pregnancy recognition had quit and 20% had reduced 1 week after termination seeking. Among those denied terminations and still pregnant, 71% had quit and 14% had reduced. In a multivariate model predicting alcohol severity, younger age, still pregnant, 1 or more previous births, later gestation, childhood physical abuse, and marijuana and other drug use were associated with lower severity; having completed college, tobacco use, and recent physical violence were associated with higher severity.

CONCLUSIONS

The proportion of the total sample drinking before pregnancy recognition is similar to national samples of women of childbearing age, while the proportion binge drinking appears higher. Of women denied terminations, who were still pregnant, the proportion having quit is similar to other populations of pregnant women. More research is needed to examine whether pregnant women may be substituting alcohol for marijuana and other drugs. Interventions focusing on alcohol use severity during pregnancy may need to also focus on tobacco.
